GenBank database
DDBJ, EBI, and GenBank are equivalent in their sequence information content. The three databases update their content every night. In this section we will focus on the GenBank database. GenBank is a database storing DNA and protein sequences. In addition to the sequence information, GenBank entries contain bibliographic and biological annotation. The number of bases in the GenBank database approximately double every 14 months. In February 2004 GenBank stores approximately 37,893,844,733 bases in 32,549,400 sequence records. The database contains 100,000 different species.
Entrez is the backbone of the NCBI database infrastructure. In is an integrated database retrieval system that enables the user to retrieve and browse datasets from the NCBI databases through a single gateway.
